Guild was destroyed by previous leader, is it possible to recover some progress

Because we had to make a new guild completely, we have to go through pit, then heroic pit, then tank, then heroic tank, then sith, and heroic sith, before we can get back to where we were with clearing speederbike raid. We are prepared to go through all of that, but figured it didnt hurt to ask to save us a month of progression that we had to do all over again.
